This 1-minute, 21-second video from 1975 shows flight and landing of the Mini-Sniffer remotely controlled, propeller-driven vehicle.
Mini-Sniffer was the first effort to build a high-altitude remotely piloted research vehicle for both Earth atmospheric studies and for possible use as a Mars aircraft. It was flown under radio control by an operator riding in the back of a pickup truck. Another vehicle carried the data recording equipment.
The Mini-Sniffer was a remotely controlled, propeller-driven vehicle developed at NASA Dryden Research Center (now Armstrong) to sample the upper atmosphere for pollution. The Mini-Sniffer represents one of the earliest attempts by NASA to monitor the Earth's atmosphere at high altitudes and was also considered for planetary atmospheric sampling flights over Mars. There were three Mini-Sniffers built. The original Mini-Sniffer was propelled by a small air-breathing engine, while a later version employed a non-airbreathing hydrazine engine for higher altitude capabilities. A large propeller was also employed because of its effectiveness in the thin upper atmosphere.
